Los cordados ( Chordata, del griego χορδωτά khordota ‘con cuerda’) son un filo del reino animal caracterizado por la presencia de una cuerda dorsal o notocorda (o notocordio) de células turgentes, 1 tubo neural hueco en posición dorsal, hendiduras branquiales y cola, por lo menos en alguna fase del desarrollo embrionario. 2 Se conocen casi 6...
A chordate ( / ˈkɔːrdeɪt / KOR-dayt) is a deuterostomic animal belonging to the phylum Chordata ( / kɔːrˈdeɪtə / kor-DAY-tə ). All chordates possess, at some point during their larval or adult stages, five distinctive physical characteristics ( synapomorphies) that distinguish them from other taxa.
Chordates, phylum Chordata, are a phylum of animals which have a notochord. The group includes vertebrates, with some closely related invertebrates . Classaxonomy. Phylum Chordata. Tunicata – (tunicates, formerly Urochordata; 3,000 species) † Vetulicolia (8 Cambrian species of fossil) Cephalochordata – (lancelets, 30 species)

29 de mar. de 2024 · chordate, any member of the phylum Chordata, which includes the vertebrates (subphylum Vertebrata), the most highly evolved animals, as well as two other subphyla—the tunicates (subphylum Tunicata) and cephalochordates (subphylum Cephalochordata).
The notochord is located between the digestive tube and the nerve cord, and provides rigid skeletal support as well as a flexible location for attachment of axial muscles. In some chordates, the notochord acts as the primary axial support of the body throughout the animal’s lifetime.
Adult lancelets retain the four key features of chordates: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail. Water from the mouth enters the pharyngeal slits, which filter out food particles. The filtered water then collects in the atrium and exits through the atriopore.
